Answer:

A chemical change is a change in what something is made of. We can tell that a chemical change has happened by looking for certain clues.

One clue is gas. Gas is produced during a chemical change. The next time you bake a cake or flip a pancake, look for the bubbles. Inside each bubble is a little bit of a gas. This gas is made when the ingredients change each other.

Bubbles help make the food you bake fluffy. If you cut into a cake, you can see the spaces where there were bubbles of gas in the wet batter.

A physical change is a change in the state of matter. There are three main states of matter - solid, liquid and gas.

If you freeze fruit juice to make a popsicle, this is a change in state. The juice changes from a liquid to a solid. Ice cream melting on a hot day is also a change in state. The ice cream changes from a solid to a liquid. The juice and ice cream are still juice and ice cream, even when they change from one state of matter to another.
